This spell enables the caster to enchant a floor, ceiling, or single wall of a room to crush intruders. The enchanted surface can be no larger than a square whose sides equal the caster’s level times 2ft. The spell activates 1d4 rounds after any creature other than the caster enters the room. The intruder must be larger than a normal rat (larger than one half cubic foot or weighing more than three pounds). When activated, the enchanted surface moves toward the opposite surface at a rate of three feet per round. Such movement does not affect the structural integrity of the room or building the surface is in. Unless the spell is canceled by the caster, the enchanted surface continues to move until one of the following happens:
A creature succeeds at a Strength check (DC 20 + caster’s appropriate ability modifier) to stop the surface from moving. Other creature may use the Aid Another action for the check by pressing against the surface as well. Creatures suffer no damage from the enchanted surface while attempting this. If the surface is prevented from moving for three consecutive rounds, the spell ends, and the surface returns to its original position.
A strong or heavy object made of stone, wood, or metal is placed in the path of the surface. If it succeeds at a Fortitude saving throw (DC 20 + caster’s appropriate ability modifier) it successfully braces the surface. If the save is made for three consecutive rounds, the spell ends, and the surface returns to its original position.
Dispel Magic or a similar spell or magic item can be used to cancel Crushing Wall.
Creatures can avoid being crushed by becoming ethereal, smaller, and so on. The Crushing Wall almost never touches the opposite surface, usually being stopped by debris. A gap of two inches or more usually remains between the surfaces.
If the wall is not stopped, it causes crushing damage to everyone in the room when the surfaces reach together at their closest. All creatures must make a Fortitude saving throw of DC 16 + caster’s appropriate ability modifier. Those who fail are crushed to death. Those who succeed suffer 5d10 points of damage. When the enchanted surface can move no farther, it returns to its original position, and the spell ends.
Material Components: a 1 inch iron cube and a walnut shell.This spell was originally from the 2e Tome of Magic
